This is an interesting thread, years ago I saw a magazine article that how a 49 yr old woman looked with her hair colored a auburn brown, something she had done for years, then they showed her with her hair grown out and not coloring. She looked younger and more alive. The reason was because as we age our skin tone lightens as does our hair color, and when she kept dying it dark brown it made her look tired.
So, I stopped coloring my hair and to help me through the grown out stage, I just did highlights on the top layer, platinum blonde hightlights and now, and it worked. Of course once I got my natural color grown out, I wanted more gray evenly, so I continue to highlight in the platinum blonde color, and by March of 2011, I will probably stop doing that because, I am ready for the real me.
I don't mind the gray but I am jealous of the women that have more of it.
So here's to, it's time for me to be me, I still act the same even with gray hair.
